CAR-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 784,361, dated March '7, 1905.

Application filed .Tune 27, 1903. Serial No. 163,420.

To (0M 7071/0111, it may concern,.-

Be it known that I, MAx STUHLnn, a citizen ofthe United States, residing at Brooklyn, in the State of New York, have invented a new and useful Oar-Indicator, of which the following' is a specification.

My invention is an improvement in streetcar indicators of that class carried by cars and indicating' the destination of the car. I am aware of the fact that such signs have been used heretofore having' in view the same object, and hence do not claim, broadly, the use of such signs.

My invention consists of the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claim, and shown in the accompanying drawings, in which- Figure 1 is a perspective view showing a sign constructed in accordance with my invention in actual use. Fig. 2 is a longitudi- Fig. 3 is a transverse section about on the lineB 3 of Fig. 2. Fig. el: is a detail elevation of one of the end brackets, a side of the bracket being removed. Fig'. 5 is a similar view of the opposite end bracket. Fig. 6 isa side elevation showing the .hinged cover that fits over the end bracket shown in Fig. 5. Fig'. 7 is an end view of the refiector. Fig'. 8 is a horizontal section taken centrally through the end bracket shown in Fig. Fig. 9 is a plan view of an indicator dial and hand. Fig. 10 is a detail sectional view of an end of the casing and a portion of a bracket,

showing in elevation the shaft and collectingrings. F1g. 11 is a horizontal section through the shaft end. Fig. 12 is a section on the line 12 12 of Fig'. 10.

Mounted upon a car is a cylindrical casing A, cut away longitudinally along' the forward side and forming a reflector. This reliector has removable end pieces A', carrying' U- shaped lugs A2. Adjacenteach end of the reliector is arranged a bracket having cui'ved feet B resting on the roof of the car, one of the feet on one side being tubular, as shown at B', through which the electric wiring is run. At one end of the casing A this supporting-bracket is in the formof a cylindrical casingl B2, and a shaft O extends through the casing B2 and into the rciiector A. The portion of the shaft within the easing B2 is squared and mounted thereon is a pinion B. An extension B" is formed on the rear side of the casing, and in this portion is journaled a vertical worm-gear B, having' a depending shaft B extending downwardly through the carroof. Thev gear B5 meshes with the pinion B3, rotating the shaft O. The bracket at the opposite end comprises a iianged disk D, having a disk D' fitting over same and bolted to the flang'e, and each disk has a U-shaped downwardly-extending slot D, thc flange I):i of the disk D being continued along' the margins of the slot. are arranged in the lower portion of the slot, and on these plates rests the outer' end of a shaft O', also extending within the reflector and carrying collector-rings D', which bear on the plates D4, respectively. box Oi", having its sides formed of glass panels O3, is arranged within the refiector and is su pported by the shafts O and O', which extend through its ends into the box, the box rotating with the shaft O, to which it is rigidly secured, 7 5

and rotating the shaft O'. At their inner ends these shafts carry incandescent-light bulbs (1*. To insure stability of the reector, lugs D" are formed on the brackets B2 and D and engag'e the lug's A2 on the ends of the refiector and S0 prevent same from rotating when the signbox is rotated to display a newv panel. On the under side of the car-roof is arranged a stationary disk E, through which the shaft B passes. hand E', which travels around the -face of the disk and indicates by its position with reference to the mark E2 which of the various panels is visible through the longitudinal opening in the reficctor. are offset with reference to each other, one of said plates being' nearer the outer end of the shaft O' and the plates being arranged upon opposite sides of the shaft O'. Oonducting-wires F, running through the foot connected to and to which plate the negative Insulated brass contact-plates D4 65 A polygonal sig'n- 7o The shaft carries an indicating- 35 rlhe contact-plates l) l 90 Wire is connected, and suitable wires F extend from one plate to the incandescent-light sockets and back to the other plate and carry the current between the plates and the incandescent-light bulbs. Vithin the casing the shaft C', which is hollow, rotates in metal rings F2, (shown in elevation in Fig. l() and in section in Figs. 8 and 11,) and the wires F5 are branched, the branches F3 leading along the interior ofthe shaft C' to the lamp C", carried by the said shaft, and the branches F4 extend through the walls or' the shaft C, properly insulated, and make sliding contact With the rings F2, and from these rings lead the exterior Wires F', which supply current to the lamp UL, carried by the shaft C.

Any desired arrangement can be adopted for the Wiring, as it is immaterial whether the lamps are arranged in series or in parallel, the particular arrangement ofthe electrical circuit not being a part of this invention, and insulation is of course used wherever requiredas, for example, between the shaft C/ and the rings D7 and F2.

The shaft B extends to Within reach of the motorman or conductor, and by rotating same to the flange, each disk having a U-shaped dowmvardly-extending slot formed therein the ange beingcontinued along the margins of the slot, insulated contact-plates arranged in the lower portion of the slot, a shaft extending into the sign-box and having its outer end journaledin the slot, rings carried by the shaft adapted to rest on the contact-plates, said plates being offset with reference to each other, and means for lighting the sign-box and means for rotating the box.
